to avoid that nasty $150 Early Termination Fee (which I understand is less than most companies) I would suggest finding an area where Sprint coverage is not available, say you are moving there, and they will waive the ETF due to the fact that they do not have the service to provide you with in that area. You would be surprised at how much area is not covered by Sprint. Some specialists may not waive fee if billing address is not changed to area outside of Sprint coverage, but many will.
